Portal-based sound propagation for first-person computer games

First-person computer games are a popular modern video game genre. A new method is proposed, the Directional Propagation Cache, that takes adavntage of the very common portal spatial subdivision method to accelerate environmental acoustics simulation for first-person games, by caching sound propagation information between portals

Entanglements of creative agency and digital technology : a sociomaterial study of computer game development

Digital technology, with its distinctive characteristics that result from the fundamental process of digitalization that underpins it, is seen as fundamentally altering processes of creativity. However, we currently have limited understanding of creativity in relation to the development of digital technology. Computer game development, with its combination of esthetic, affective and cultural use features and highly sophisticated digital technologies, is a valuable setting for investigating these issues. In this paper, we explore how computer games are shaped through the interplay between the creative intentions of developers and the digital technologies involved in their production and playing. Drawing on in-depth studies conducted at three leading computer game development studios and a leading producer of the software system used in game development, this paper shows how the game developers' creative ideas for imagined novel game-playing experiences relate to a) the development of relevant digital technologies, and b) the emergence of new game development practices. The article goes on to propose a view of creativity as an on-going flow that, following an initial ‘creative impulse’, ripples through the sociomaterial entanglements of a particular setting, reconfiguring them in the process and spreading out in time and space in often unexpected ways

REGULATION OF THE INTERACTIVE DIGITAL MEDIA INDUSTRY IN SINGAPORE

The latest “buzz” in Singapore is interactive digital media (IDM), a diverse industry that includes technologies such as video games and interactive advertisements. In January this year, the Singapore government announced that it would target the IDM sector as one of the key growth areas for the future, and provide the infrastructure for Singapore to be educated in and exposed to this new technology.1 The Singapore government has openly committed to setting aside S$500 million over the next five years to develop this industry.2 And to deal with the social, technical, legal and regulatory implications of this industry, on 1 April 2007, the Singapore government also set up a high level advisory council which will make recommendations to the government on how these issues will be managed while keeping pace with the development of this industry in Singapore.3 While the Advisory Council on the Impact of New Media on Society4 studies and deliberates on the issues, the existing legal and regulatory framework that continues to apply to new media has been described as based on a “light touch” approach. This paper seeks to summarise the existing position in Singapore, and tries to describe the policies and philosophies behind the “light touch” approach as elucidated from the laws and regulations in Singapore

Virtual Reality Games for Motor Rehabilitation

This paper presents a fuzzy logic based method to track user satisfaction without the need for devices to monitor users physiological conditions. User satisfaction is the key to any product’s acceptance; computer applications and video games provide a unique opportunity to provide a tailored environment for each user to better suit their needs. We have implemented a non-adaptive fuzzy logic model of emotion, based on the emotional component of the Fuzzy Logic Adaptive Model of Emotion (FLAME) proposed by El-Nasr, to estimate player emotion in UnrealTournament 2004. In this paper we describe the implementation of this system and present the results of one of several play tests. Our research contradicts the current literature that suggests physiological measurements are needed. We show that it is possible to use a software only method to estimate user emotion
